SICANIP deposits are part of composite materials. They are formed by immersing a part to be coated in a chemical nickel plating bath containing fine silicon carbide particles held in suspension by agitation. SICANIP consists of a tough nickel-phosphorus alloy matrix embedded with fine particles of silicon carbide (SiC). The addition of hard SiC particles (2500 HV) to the deposit makes it extremely resistant to abrasion and friction.<\/span><\/p>\nThe final hardness of the coating results not only from the chemical bonds formed between the silicon carbide particles and the electroless nickel matrix during heat treatment, but also from the structural hardening of the nickel-phosphorus matrix.<\/p>\n
The SICANIP coating is slightly abrasive in its unprocessed state. This often requires the machine operator to run in the deposit. To avoid this running-in phase, we can coat SICANIP with a thin layer of LUBRINIP BN, which has a very low coefficient of friction, guaranteeing immediate use at full speed without running-in.<\/p>\n<\/div>
